Skyrmions and the nuclear force [PDF]
Physical Review C, 1993 The derivation of the nucleon-nucleon force from the Skyrme model is reexamined. Starting from previous results for the potential energy of quasistatic solutions, we show that a calculation using the Born-Oppenheimer approximation properly taking into account the mixing of nucleon resonances, leads to substantial central attraction.

Nonuniform gyrotropic oscillation of skyrmion in a nanodisk
AIP Advances, 2018 It was predicted that magnetic skyrmions have potential application in the spin nano-oscillators. The oscillation frequency is a key parameter. In this paper, we study the skyrmion relaxation in a FeGe nanodisk and find that the oscillation frequency ...

Thermal Collapse of a Skyrmion
, 2023 This repository contains data and scripts used in Ref. [1]. There, the thermal collapse of a magnetic skyrmion is explored by computing the time evolution of 100x100 spins in a two-dimensional lattice using the Landau-Lifshitz-Langevin equation.

Light‐Modulated Exchange Bias in Multiferroic Heterostructures
Electron, EarlyView.In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.

Quantum fluctuations stabilize skyrmion textures [PDF]
, 2015 We study the quantum spin waves associated to skyrmion textures. We show that the zero-point energy associated to the quantum spin fluctuations of a noncollinear spin texture produce Casimir-like magnetic fields.
